An immediate expansion of unrestricted submarine warfare would still depend on the submarines and support facilities Germany had available. The proposed British response is to turn the carrier force against U-boats and their docks after attacking the battle fleet. These boats operate from ordinary docks rather than the massive concrete pens built in the Second World War. A bomb damaging a submarine on the surface could prevent it from submerging, so these attacks would not require the Cuckoo's aerial torpedo. The intended result is to restrict submarine operations by striking the boats where they are exposed.

Bombing U-boat docks after a carrier victory
Exposed U-boats and ordinary docks would offer follow-up bombing targets before the construction of massive protected pens.
